FLYING-MACHINE.

Specification of Letters Patent.

Patented Sept. 7, 1915.

Application filed October 16, 1914. Serial No. 866,905.

To all Ir/mm it 112 1 concern Be it known that I, Cnxunxcn (i. VALKER, a citizen of the l'nited States, and a resident of Bramwell, in the county of Mercer and State of \Vest Virginia, have invented certain new and useful Improvements in Flying-Machines, of which the following is a specification.

My invention relates -to heavier than air flying machines, and the main object thereof is to provide such a device which closely imitates the flight of birds.

After careful study of the flight of birds I have reached the conclusion that such flight is rendered possible by setting up a rotary, twisting, motion in the air, by means of the wings, beneath and behind the bird,

- swirling air currents by mechanical means,

which means forms the basis of the present application for patent.

My invention is fully described in the following specification, of which the accom panying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in which Figure 1 is a front view, largely diagrammatic, of a flying machine embodying my principles; Fig. 2 is a section thereof on the line 22 of Fig. 1; Fig. 3 is an enlarged sec tionalf detail; and Fig. 4 is a section taken on the line 44 of Fig. 3.

In the drawings forming a part of this application I have illustrated one form of embodiment of my invention, comprising a suitable frame 5 having a motor 6 thereon, a seat 7, control lever 8, control wheel 9, control pedals 10, direction rudder 11 controlled by the wheel 9 and cables 12,'and altitude rudder 12 controlled by the lever 8, but these features are, as stated, largely diagrammatic and subject to change. The

rearward end, the forward end being entirely open, and said rearward end may be closed if desired, although shown open.

Arranged between the cylinders 13 area plurality of rearwardly and downwardly deflected planes 15 which have a sustaining and elevating effect, and are, in the form shown, in rigid positions with respect to the frame and cylinders; pivotally mounted, at 16, to the outer surfaces of the cylinders 13, are a plurality of ailerons 17 which are connected, one series with the other, by means of a cable 18 suitably guided over posts 19 in such manner that downward movement of one'series carries the other series upwardly, this movement being accomplished by means of cables 20 connected with the pedals 10, or

in any other desired manner of control.

lVi'thin each cylinder 13 is a' centrally arranged shaft 21 geared in any desired manner with the motor 6, by means of sprockets and chains 22 in the form illustrated, and the direction of rotation of said shafts mav be in the same direction or in different directions, and at the same speed as the motor shaft, or at a different speed, as desired or found expedient. Also secured to each shaft are propeller blades 23 of the usual or.

any desired construction and of any desired number on each shaft, but said blades are revoluble within the corresponding cylinder, for a reason later pointed out; each of said shafts 21 also carries two stabilizing blades 24, each of which is directed rearwar dly of the machine and upon a parabolic curve the general direction of which is at an incline to the shaft, said blades being, in cross-section, concavo-convexo, as shown in Fig. 4, and said parabolic blades are arranged at an angle to the propeller blades, in the form shown. These stabilizers are feather shaped, and are copied from the large wing feathers of a turkey or chicken, and I claim that the blades 24, in their revolution about their axes while in the correct position, will balance a body upon which they are carried elements for sustained flight. The parabolic blades 24 may be actuated in unison with the-propeller blades 23 or they may be independently actuated, as will be understood.

In operation, the air is forced into the cylinders 13 under great pressure by the propeller blades, and this air under pressure escapes through the openings ll and beneath the ailerons 17 thus tending to raise the machine when both series are downwardly deflected, the lifting effectbeing in the degree of such deflection and of the air pressure coming from the cylinders 13, andthe air from the propeller blades thus not only forces the machine ahead, but

it also tends to sustain the machine in the air because of the ailerons 17, and all the efficiency of the motor is utilized in producing flight The cylinder, as stated, may be closed at the rear, orit may be open as shown, and a supplemental propeller placed thereat, and I may also provide a control for regulating the size of this opening to assist in the control of the machine, and other changes in and modifications of the details shown and described may be made, within the scope of the following claims, without departing from the spirit of my invention, orsacrificing its advantages.

Having fully described my invention. what I claim as new, and desire to secure by Letters Patent, is

1. A flying machine, comprising a frame,

a motor, propellers geared thereto, main.

planes, rudders, ailerons, control means, two cylinders in a longitudinal plane of said machine, provided with slots adjacent the under surfaces of corresponding ailerons, and means for causing whirling currents of air through said cylinders, to stabilize said machine.

2., A flying machine, comprising a frame, a motor, propellers, main planes, rudders, ailerons, and control means, two cylinders in a longitudinal plane of said machine, provided with slots adjacent the under surfaces of corresponding ailerons, a shaft for each propeller in the respective cylinder, and means on each shaft for causing a whirling current of air through the corresponding cylinder and the slots therein.

3. A flying machine, comprising a frame, a motor, propellers, main planes, rudders, and control means therefor, two cylinders arranged longitudinally of said machine and provided with slots in the sides thereof, an aileron pivoted to the outer side of each cylinder, above said slots, means for verti- (sally deflecting said ailerons, and means for causing a whirling current of air through each cylinder and the slots therein.

4. A flying machine, comprising a frame, a motor, propellers,.main planes, rudders, and control means therefor, two slotted cylinders arranged longitudinally of said machine, an aileron pivoted to the side of each cylinder'above the corresponding slot,

means for moving said ailerons, a shaft in each cylinder, and a plurality of parabolic blades carried by each shaft to cause a whirling current of air through the corresponding cylinderand the slots therein.

5. In a flying machine, a motor, a cylinder, a shaft in said cylinder in operative connection with said motor, and a plurality of parabolic blades arranged longitudinally of said shaft and carried thereby, for causing a whirling current of air through said cylinder to stabilize said machine, each of said blades being in an axial plane of said shaft for the full length of said blades.

6. In a flying machine, a motor, a cylinder, 'a shaft in said cylinder in operative connection with said motor, and a plurality of parabolic blades arranged longitudinally of said shaft and carried thereby, for causing a whirling current of air through said cylinder to stabilize said machine, each of said blades being convex on its outer surface and concave on its inner surface. and said concave surfaces facing said shaft and each other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
